ATOMIZER Filed Feb. 15, 1943 INVENTORS Jo 5. Schm/fl MW/am ff. DoddsATTORNEY Patented Sept. 12, 1944 OFFICE ATOMIZER v Joy B. Schmitt andWilliam R. Dodds, Toledo,

Ohio, assignorsto The -De Vilbiss Company, 7 Toledo, 0hio,.a.corporation of Ohio Application February 15, 1943, Serial No.47ao14 4}Claims;

This invention relates toatomizers designed particularly for theapplication of medicinal'prep arations but which are suitable forapplying other Still another object of our invention is to provide anatomizer in-which the liquid preparation flows through the bottom of thecontainer to the discharge tube, and one so constructed that no liquidwill leak from the nozzle when the atomizer is in its ordinary uprightposition.

Other important objects of our invention will be apparent from a readingof the following description in connection with the drawing wherein, forpurposes of illustration, we have shown a preferred embodiment of ourinvention.

In the drawing Fig. 1 is a side elevation of the embodiment;

Fig. 2 is alongitudinal sectional View taken through Fig. 1;

Fig. 3 is a section of the atomizer nozzle taken on a line '33 of Fig.2; and

Fig. 4 is a section of the air and liquid tubes taken on a line 4-4 ofFig.2.

Referring in detail to the drawing, the atomizer has a main body portionI which has an upper cuplike cavity 2 for holding the medicine This isclosed by cap piece 3. Integral with the body is a conical supportingapron 4 upon which the atomizer rests. Through the body portion! is aninclined passage 5. Into this from one side is inserted air nipple 5, tothe outer end of which.

is :fastened air bulb 1. At the rear of the air bulb I is an air checkvalve 8 of conventional design,

permitting the entrance of air into the bulb when the bulb expands andpreventing a flow of air out through the valve on compression of thebulb.

In the front end of nipple B is pressed a long air tube 9.

To the same 'end of the nipple 6 extending through the body I isthreaded a liquid tube at in Fig. 3, providing three grooves for thefluid to pass through foo reach the nozzle discharge opening I l at theend of tube ID. V

After the proper amount of the medicinal prep arations has beenintroduced into the receptae cle portion 2 by dropper or othermeans,.the cover 3 may be putin place to prevent spilling. This cover 3should either fit loosely enough to provide a slight space for airtoenter the cup or should have a small vertical groove in the skirtportion' to act. as a vent passage. 'If it. follows the natural flowinduced by gravity, at least some o f the medicament will pass down fromthev cup through the port [2 to angular groove 13 in the air nippleiFrom this groove [3 two opposed passages l4 extend to, thev longitudinalpassage I5. From here'the medicine will flow up toward the dischargeopening ll through the extension of passage 15 to a point within tube [0where it is level with the surface of the medicinal preparationremaining in cup 2. p

The tube II] is so inclined upwardly that its top point is level withthe top of cup 2. This prevents the liquid from flowing out of tip llwhen the atomizer is in its normal upright position. When it is desiredto use the atomizer, the tip is inserted into the mouth or nasal cavity,

of air and liquid occurring at port ll results in the atomization of theliquid.

The general desi n of the atomizer makes it compact. The bottom outletof the receptacle permits the drainage of all medicine therefrom. Thisis not possible from the ordinar atomizer which has an outlet tubeextending down into its receptacle. Some medicine is ordinarily leftbeneath the end of such outlet tubes.

The one piece body portion is inexpensive to manufacture and provides afine supportin base for the bulb on one side and the discharge tube onthe other without any threaded engagement directly with either of them.

The bulb and air'assembly by threaded engagement with the tube I0 isheld against body portion .I. Nipple 5 fits tightly into the body,thereby preventing any leak of the liquid.

Although we have shown and described herein a preferred embodiment ofour invention,,it is'definitely to be understood that we donot desire tolimit the application of the invention thereto, and various changes maybe made in the structure and arrangement of parts without departing fromthe spirit of our invention and avoiding the scope of the followingclaims.

We claim c j 1. In an atomizer for applying a single dose ofmedicineorthe like, a body piece having a cuplike cavity at its top and asimilar inverted cavity at its bottom,- the upper cup forming areceptacle for the medicine and the bottom edge of the bottom cupforming the supporting base for the atomizer, an inclined passagethrough the center of the body portion between the cups, a

nippleextending through the passage from its, lower end, an air bulbfastened to the outer end therewith for the preparation, "an upwardlyinclined bore through the body, a ertical passage into the borecommunicating withthe receptacle,

an outwardly facing shoulder at each end of the bore, an air supplynipple extending into the bore from its lower end and seating againstthe'shoul-' tr'ally into and through thellquid dischargetube to carryairto the discharge end of said tube.

3. An atomizer for spraying medicinal preparations and the like,comprising a body, a recep tacle of restricted size in the upperportionof the body with an outlet in itsbottom, an elongated nozzle hayingcommunication with the receptacle outlet and extending in a straightline from the body below the receptacle to a point above the normallevelof the liquid inthe receptacle, a flaring supporting base integral withQ the body and an air supply bulb fastened to the body on the oppositeside of, but in line with the elongated discharge nozzle and havingcommunication with the nozzle to supply it with atoniiz ing air. L

4. In a medicinal atomizer of the type described, a body, a receptaclefor medicine attached to the body, a transverse bore through the body,an outwardly facing shoulder at each end of the bore, an airsupplynippleseating against der at that end, an elongated liquid discharge 7 tubeextending from the opposite end of. the bore and held against theshoulder at that end through a connection'with the air supply nipple, apassage in the air supply nipple for delivering the preparation to theliquid discharge tube and an extension of the air, supply nippleextending cenone of the shoulders, an elongated discharge nozzle heldagainst the other shoulderby'a connection through the bore with the airsupply nipple, an elongated air tube fastened to thenipple andextendingtherefrom through the bore and centrally intoand toward the outer end ofthe discharge nozzle, a passage between the receptacle and the bore todeliver medicineto the nozzle, and an air bulb connected to the nipplefor supplying atomizing air through the air tube to the nozzle.
